Leque Island is a small island located in Snohomish County, in Washington, United States. It can be found just beneath the bridge between Camano Island and Stanwood, at the mouth of the Stillaguamish River, in Puget Sound. Like the larger Florence Island, Leque is part of the Stillaguamish river delta. The island is formed where the Old Stillaguamish River Channel bifurcates at Leque's Point, with the South Pass flowing into Port Susan and the West Pass emptying into the southern end of Skagit Bay. Leque is separated from Camano to the west by Davis Slough.
